The nameplate capacity is 400MT per day and is design to run 335 days a year

The plant has a co generation system using 30 Bars superheated steam and 11 MT per hour to produce 520kVA of self generated electricity to run its main sulphuric acid circulation pump and main cooling water circulation pump.

There are two blowers: the start up blower and the main blower: main blower is powered by steam turbine based on 22-30 Barg of superheated steam @17 -22 MT per hour. Source of steam is from waste heat boiler and steam superheater

The converter is charged with vanadium pentoxide catalyst supplied by Topsoe Haldoe. The design is 3 + 2 conversions. Last known overall conversion is 98% based on SO2 weight for weight basis.

There is a drying tower irrigated by sulphuric acid to produce dry air for combustion of sulphur

The steam coils in the sulphur pit are made of 316LSS

The acid pipe lines are supplied by Chemetic International with trade name “Saramet”-it resist corrosion at temperature below 103°C.

The acid circulation tank is lined with acid proof bricks

The main acid circulation pump is supplied by Lewis Pump of St Louis

There are two sets of cooling towers: one for cooling sulphuric acid and the other is to recover the excess steam from the co-generation system.

The main acid coolers and the heat exchanger for preheating of acid is anodically protected. Supplied by Chemetic International.

The gas to gas coolers are made of 304SS and manufactured by Chemetic International.

The control system for the acid plant is a DCS by Yokogawa.

Preheating system is based on LPG for shorter time taken for start up.

The tail gas is scrubbed with caustic solution in a gas scrubber system before emitting into the environment. There is a SO2 gas monitoring system to keep a record of the level of SO2 emitted into the atmosphere.
